Title: Improvements in or relating to float operated needle valves
Inventor: THURSTON BRIAN OLIVER
IPC: F16K31/26
Filed: 1960-01-21
Abstract: 911,315. Valves. SANGAMO WESTON Ltd. Jan. 23, 1961 [Jan. 21, 1960], No. 2273/60. Class 135. A float-operated needle valve 18 controlling the supply of liquid to a chamber 10, e.g. for supplying fuel oil through an outlet pipe 12 to oil burning equipment, is normally opened and closed in response to movement of the float 13 to maintain a level " l " in the chamber, and in the event of the float or level sinking below a predetermined limit, e.g. owing to puncturing of the float, the valve is closed by a supplementary closing means released by a trip mechanism operated by the float. The supplementary closing means may also be tripped on rising of the float above a predetermined limit to supplement the normal closing action of the float and ensure complete shut off. As shown, in normal operation an extension 16 of the float arm 14 beyond its fulcrum 15 bears on the underside of a weight 17 fixed to the needle valve 18. On falling of the float below a predetermined limit, a projecting tooth 40 formed on the fulcrum region of the arm 14 engages an inturned catch lug 37 on a short limb 36 of a lever arm 35 pivoted at 32. A long limb 38 of arm 35 consequently engages an abutment surface 41 of a slot in an outwardly-turned lug 39 on one of two side arms 22 of a release lever 21 which is freely pivoted on the fulcrum 15 and has an extension 24 carrying a latch 25 which engages a notch 26 on the free end of an extension arm 27 of a hammer device 28 also pivoted at 32. This hammer device is loaded by a spring 33 and carries a striker 30 adapted to contact the end 34 of the valve 18 to overcome the weight of the float 13 and close the valve. On rising of the float above another predetermined limit, the arm 14 engages a platform 23 connecting the side arms 22 to disengage the latch 25 and apply closing force to the valve to supplement the buoyancy of the float and ensure complete closure. The spring hammer 28 may be replaced by a gravity operated device. The outlet pipe 12 is set at a level which prevents operation of the trip simply by drawing-off fuel.

Title: Polyimide powders
IPC: C08J3/12
Filed: 1963-01-18
Abstract: A polyimide powder having an average surface area of at least 0.1 square metre per gram, the polyimide having an inherent viscosity of at least 0.1 measured in a solution of 0.5% of the polyimide in sulphuric acid at 30 DEG  C. and having the recurring unit <FORM:0981543/C3/1> where R is a tetravalent radical containing at least one ring of six carbon atoms having benzenoid unsaturation, the four carbonyl groups being attached directly to separate carbon atoms in a ring of the R radical and each pair of carbonyl groups being attached to adjacent carbon atoms in a 6-membered benzenoid ring of the R radical, and R1 is a divalent polycyclic aromatic radical in which no more than one valence bond by which R1 is attached to a nitrogen atom of said recurring unit is located in any one aromatic ring, is made by reacting at least one organic diamine H2N-R1-NH2 with at least one tetracarboxylic acid dianhydride of the formula <FORM:0981543/C3/2> in an organic solvent for at least one of the reactants, said solvent being inert to the reactants, at a temperature below 175 DEG  C., precipitating the resultant polyamide-acid with a precipitant and treating the polyamide-acid powder with an anhydride of a lower fatty monobasic acid preferably in the presence of a tertiary amine to effect ring closure.  The precipitant may (when it is a dehydrating agent) react with the polyamide-acid to produce a powder that is predominantly polyimide. Finely divided fillers, e.g. metals, metal oxides, minerals, abrasives, glass or polytetrafluoroethylene, may be combined with the polyamide-acid or the polyimides. Examples are given.

Title: An Improved Mechanically-operated Signal Indicating Device.
Inventor: DUDGEON ARTHUR EDWARD TILSTONE
IPC: B66B19/06
Filed: 1917-02-15
Abstract: 113,151. Dudgeon, A. E. T. Feb. 15, 1917. Mine and colliery signals.-A signalling-device particularly for mines has two pointers moving over the same dial, one operated by the banksman and the other by the onsetter. Operation of either pointer cancels the previous indication of the other. Both may be returned to zero when a signal has been complied with. Each pointer moves two steps for each signal indication so that " hanging " is visibly indicated by a pointer making half a signal movement. The pointers (not shown) are operated by corresponding wheels b, d having teeth or pins m, n, engaged by pivoted counterweighted members 3, 4, carried by sliding members w reciprocated by the oscillations of corresponding levers p to which the signal impulses are imparted. During the upward movement of a member w, the corresponding wheel is moved half a signalling step by the member 3, and the signalling step is completed by the member 4 during the return movement. Each member w carries a. projection 7 engaging under an arm 8 secured to a shaft 9 which is thus oscillated at each signallng impulse. When a signal is being registered by one pointer, each impulse causes an arm 8 to raise the weighted ends 5, 6 of the members 3, 4 co-operating with the wheel of the other pointer, so that these members 3, 4 are disengaged from the wheel. Thus a previous signal registered by the other pointer is cancelled, the wheels w, when released, being returned to the zero position by weights carried by chains g, h. Both pointers may be returned to zero by a handoperated member 17 carried by the shaft 9.

Power is switched to selected solenoids 13a & c, and to a selected coil 27a or 27b by means of thyratrons 26a to 26j, Fig. 3. The pulse gating means also includes flip-flops 55, 61, 63 and 67, Fig. 1, an OR gate 57, delays 56, 58, a pulse shaper 59, a normally - closed switch 62 and switches 64 and 68. Flip-flop 55 in conjunction with the AND gates 39 and 41 functions to alternately switch the power to the control 12 and the control 29. The alternate powering of the solenoids 13a & c. and coils 27a, 27b occurs at the leading edge of each positive half-cycle of the A.C. power and extends for the remainder of the positive half-cycle. Flip-flop 61 in conjunction with the AND gates 39 and 41 functions as a time cycle for the tape movement. Flip-flop 63 in conjunction with switch 64 determines the direction of movement of the tape. Flip-flop 67 in conjunction with switch 68 determines whether or not perforation is effected. The tape may be moved indefinitely without perforation by opening switch 62. In a modification, Fig. 4 (not shown), each thyratron has a single control grid which is connected to an AND gate.

Title: Improvements in and relating to electric lamp fittings for panel illumination and the like purposes
Inventor: STEVENS BERTRAM
IPC: H01R33/00
Filed: 1955-01-26
Abstract: 784,752. Lamps for illuminating panels. THORN ELECTRICAL INDUSTRIES, Ltd. Jan. 10, 1956 [Jan. 26, 1955], No. 2391/55. Classes 75(3) and 75(4) An electric lamp fitting comprises a hollow cylindrical casing 14 adapted for the insertion of a lamp 11 through one end thereof to engage electric contacts 19, 20 within the casing and one or more electrical connecting means such as metal strips 21, 22 connected to the contacts 19, 20 and passing through apertures 23, 24 in the other end of the casing, the casing being secured in an aperture in a panel 13 so that a sealing washer 17 is compressed between an outwardly projecting flange 15 on the casing and the panel 13 and a rubber member 25 sealing the end of the casing through which the connecting strips 21, 22 pass. The flange 15 is clamped in a boss 16 on the panel by a ring 18 screwed into the boss. The rubber member 25 is cylindrical and has on one end face lugs 26, 27 with slots therein for the passage of the connecting strips 21, 22 and on the other end face an annular ridge which is flattened against the end face of the casing 14. A cylindrical metal cap 28 having an edge crimped into a groove 30 in the casing 14 presses the rubber member 25 against the end of the casing. The base of the cap is apertured for the passage of the lugs 26, 27 and is inwardly dished so that it exerts pressure on the rubber member 25 in a region around the lugs 26, 27 to close the apertures therein for the connecting strips. The lamp 11 is mounted in a lampshade comprising an opaque knob 31 screwed into the clamping ring 18 and carrying a metal shell 33 provided with windows and having a slotted end part which engages the lamp and also engages within the contact member 20.

Title: Improvements in or relating to the preserving of fresh fruits
IPC: A23B7/04
Filed: 1931-01-26
Abstract: 368,013. Cooling fruit; refrigerating. COMER, W. T., Box 1191, Atlanta, Georgia, U.S.A. Jan. 26, 1931, No. 2469. Convention date, Jan. 27, 1930. [Class 29.] Fruit is preserved by rapid freezing at temperatures of the order of - 50‹ C. and subsequent storage at temperatures below 0‹ C. Apparatus for freezing the fruit may comprise a flat chamber 12 having hollow walls 10, 11 through which compressed carbonic acid or other refrigerant is expanded from inlets 19, 20 to outlets 21, 22. Carbonic acid snow forms and evaporates within the walls, which are externally heat insulated. The fruit may be spread on a tray in two hinged parts 23, 24, one part being located in the chamber 12 while the other part is being loaded. After freezing is complete the tray is moved to bring the second part into the chamber, the first part falling so as to discharge the frozen fruit by gravity. Flexible sealing strips 32, 33 are placed at the ends of the chamber 12. In a modification an endless conveyer with spaced ribs is used instead of a reversible tray, and the refrigerant is admitted at the delivery ends of the hollow walls. The apparatus may be adjustably inclined to vary the duration of the freezing operation, which is of the order of one to four minutes.

Title: Improvements in and relating to Carburetters.
Inventor: DODSON EDWARD
IPC: F02M7/28
Filed: 1918-02-12
Abstract: 125,687. Dodson, E. Feb. 12, 1918. Spray carburettors.-A carburettor, particularly for use on aircraft, in which normally the fuel supply would be over-corrected, has two air passages, one, of relatively small dimensions, referred to a.s a secondary air passage, and another of larger dimensions and always in action and referred to as a primary air passage. Fuel is fed from the float chamber to primary fuel orifices in the secondary passage by a pipe, a branch from which, or from a separate supply. leads to a nozzle in the main passage at or near its point of maximum constriction or, in the case of a mixed-flow type of carburettor, the branch may be merely an air pipe connecting the constricted part of the primary air passage with the fuel space of the main orifices. The secondary air passage supplies the engine with an efficient mixture for cruising speeds, and the fuel supply leading into the main air passage is brought into action when additional power is required irrespective of efficiency. In the construction shown in Fig. 1, the seconday air passage is in the form of a Venturi tube 8 co-axial with and enclosed by the main air passage 5. Fuel is fed to orifices 13 by a pipe 11, and a pipe 14 supplies a nozzle 15 located at or about the constricted portion of the main passage 5. As the engine speed increases, the air flow through the secondary passage, owing to friction, ultimately reaches a maximum and the mixture strength from this point, due to air flowing through the main passage, would become weaker but for the nozzle 15, which then begins to discharge fuel which keeps the mixture strength constant. In a modification, the auxiliary air passage enters the main passage at right-angles at about the point of maximum constriction. In the mixed-flow type of carburettor shown in Fig. 3, a pipe 36, with valve 37, connects the maximum constriction portion with a space 34 around the spraying orifices 31. At low speeds, sufficient air is drawn through pipe 36 to keep down the flow of fuel, but, at higher speeds, this air flow ceases and in fact may reverse its direction and convey. additional fuel to the nozzle 35. In a modification of this construction, the pipe corresponding to 36 leads to a fuel well fed from the float chamber through a restricted orifice and is also in communication with the constricted portion of the primary air passage and with a pipe in the main air inlet 5 from which a pressure-balance pipe may lead to the top of the float chamber. The nozzles such as 15, Fig. 1, and the constrictions in the various pipes may be replaced by others of different bores.
